Explanation:

Step1: Analyze \((NH_4)_2S\)

In \((NH_4)_2S\), the subscript of \(NH_4\) is 2, and each \(NH_4\) has 4 H atoms. So H atoms from \((NH_4)_2S\): \(2\times4 = 8\).

Step2: Analyze \(Ca(OH)_2\)

In \(Ca(OH)_2\), each \(OH\) has 1 H atom, and there are 2 \(OH\) groups. So H atoms from \(Ca(OH)_2\): \(2\times1 = 2\).

Step3: Sum the H atoms

Total H atoms on left side: \(8 + 2 = 10\).

Answer:

10
